Do not think you do NOT know that which you think you do not know. You actually DO know most of what you think you do not know. The simple truth is that you paid scant, or NO attention, when first you heard or saw that which you now think you do not know. Sadly, the things you ought to know, which you now think you do not know, are far greater than the things you think you know. Always focus - ALWAYS REFLECT, ... or else you will REGRET. (The Pessimistic Philanthropist)
